Specification forming part of Letters Patent No. 133,885,1dated December10, 1872.

same, and which said drawing constitutes part of this specification, andrepresents, in-

Figure 1, a side view; Fig. 2, a top view,

y with a partial section; Fig. 3, a transverse section on line w a',enlarged; and in Fig. 4, the process of construction.

This invention relates to an improvement in vthe construction ofshade-holders for lamps.

Usually the wires which extend from the ring around the lamp-top to theshade-ring have been attached to the former by extending the wiresthrough the ringand riveting the end, a shoulder having been firstformed on the end of the wire for the purpose. To facilitate theoperation and more permanently secure the wires is the object of thisinvention; and it consists in forming the ring which embraces thelamp-top withl an annular Corrugation, into which the ends of the wiresare-set, the said ends being previously bent at nearly right angles soas to lie in the corrugations, then closing the metal of the ring downonto the bent ends of the Wires, as more fully hereinafter described.

A is the shade-holder ring orplate, ofthe usual form, which is supportedfrom a ring,

B, around the lamp-top by means of wires C, more or. less in number,extending from-the said ring B upto the ring A. These wires have usuallybeen riveted to each of the two rings, the ends of the wires formed witha shoulder and extending through perforations in the ring for lthepurpose. The ends through the ring B must necessarily project somewhat,and it is dicult at that point to rivet the wires so perfectly that theywill not interfere with the setting of the ring B onto the lamp-top, andthe riveting is necessarily so slight that it renders the wires liableto become detached. To overcomel this difficulty I form the ring B, asseen in Fig. 4, with a corrugatid'n, a, extending around the ring.projecting outwardly, and perforate this corrugation at the point wherethewires are to be inserted. The wires at the ends which are to beattached to the ring are bent to the right or left, as seen at d, Fig.2, so as to lie within the corrugation; then, by suitabler dies, thiscorrugation is closed down onto the ends of these wires, as in Fig. 3,forming a head, D, around the ring B, as seen in Fig. 3. Thisconstruction prevents the wires from turning, and they cannot bedetached'from the ring B without destroying the ring. The other ends ofthe wires are attached to the ring A in the usual manner.

l I claim as my invention- 'The' herein-described shade-holder, consist'ing of the shade-supporting ring A and ring B, by which it is attachedto the burner, and the .wires C extending from the ring B up to andsupporting the ring A, when the said wires are secured to the ring B bymeans of an arm turned from the said wires to the right or left and thering B closed down on the said arms, substantially as described.
